6308-2RS1/W64 Bearing Product Overview & Core Advantages
The 6308-2RS1/W64 is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This metric bearing features integrated sealing (2RS1) and a solid lubricant (W64), making it a maintenance-free solution ideal for environments where re-lubrication is difficult or impossible. Its design excels at handling significant radial loads while also accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and long service life, offering a robust and cost-effective choice for a wide range of industrial machinery.
Model Code Breakdown
- 6308: Standard designation for a single row deep groove ball bearing with a 40mm bore and 90mm OD.
- 2RS1: Indicates contact seals on both sides. The "RS1" suffix denotes nitrile rubber (NBR) seals that provide effective protection against contaminants and retain lubricant.
- W64: Signifies that the bearing is pre-lubricated with a Solid Oil polymer compound. This filling provides a consistent lubricating film, is resistant to wash-out, and enables the bearing to operate across a wide temperature range from -30°C to 120°C.
6308-2RS1/W64 Bearing Structural Features & Performance Benefits
The performance of the 6308-2RS1/W64 is derived from its specific construction:
- High Load Capacity & Rigidity: The deep groove raceway and robust chrome steel construction (rings, balls, and cage) provide a high radial dynamic load rating of 915 lbf and a radial static load rating of 5395 lbf, ensuring stable operation under load.
- Sealed & Maintenance-Free Operation: The double-sealed (2RS1) design effectively excludes moisture, dust, and other contaminants. Combined with the Solid Oil (W64) lubrication, this eliminates the need for re-lubrication, reducing maintenance costs and downtime.
- Optimized for Consistent Performance: The solid polymer lubricant does not leak or degrade like traditional greases, ensuring consistent performance and preventing contamination of sensitive processes. The standard CN radial internal clearance and ABEC 1 precision make it suitable for a vast majority of general industrial applications.
6308-2RS1/W64 Bearing Typical Application Areas
This versatile and robust bearing is commonly specified in:
- Electric Motors and Gearboxes
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
- Food & Beverage Processing equipment where wash-downs are common
- General machinery requiring a reliable, sealed ball bearing
